FEATURES
DESCRIPTION
lSingle Fiber Bi-Directional Transceiver
l1550 nm DFB LD Transmitter
l1310 nm Receiver
The BTRS-7720C series is high performance module for
single fiber communications by using 1550 nm transmitter
and 1310 nm receiver. The transmitter section uses a
multiple quantum well 1550 nm DFB laser and is a class 1
laser compliant according to International Safety Standard
IEC-60825. The receiver section uses an integrated 1310
nm detector preamplifier (IDP) mounted in an optical
header and a limiting post-amplifier IC. A PECL logic
interface simplifies interface to external circuitry. LV-TTL
Signal Detect is used.
